Bayesian Inference analysis tree under general time-reversible model of sequence evolution with correction for invariable sites and a gamma-shaped distribution model (GTR + I + G) from known and the newly sequenced Neothada hades and N. major based on sequences of the D2-D3 expansion fragments of the 28 S rDNA region. Bayesian posterior probabilities (50%) are given for each clade. Scale bar shows the number of substitutions per site.
